They fit both my kids well. My daughter is 23lbs at 9 months and has been wearing them for at least two months now. The leg was a bit loose to begin with but we never had any leaks. Now they fit perfect on the tightest leg snap and second to tightest waist. They also fit my 39/40lb almost 3 year old on the second to last snap. The rise is still good on him and he is pretty tall for his age. I use them over night with a doubler stuffed in for him sometimes since he is day trained, but he rarely wakes to pee at night.
I am building up a good stash of them since they are my all time fav

I think they are trimmer than the one size, but the rise is about the same. Someone correct me if I'm wrong

They fit my long and lean DD at 30 pounds and my short and chunky DS, also at 30 pounds. It's probably the most versatile diaper we've had. If you were going to use on a toddler at night I'd definitely add inserts though.

How big do the mediums fit? I have one on the way but haven't tried yet obviously. There is a lady selling 3 more mediums and I am tempted but not if my girl will outgrow them right away. If we are on the tightest setting in large what will the medium be like? The rise is good but pretty tall on her right now in large.

I have one and wish I had more. I like how trim it is between the legs- dd will not wear things that are wide at all- she got too used to sposies during my "cd break" She is 36 inches 33 pounds. I have not yet tried it at night
I hope they go on sale again- wish I would have gotten way more right after Christmas
